Abstract

Bacteroides fragilis was analysed by pyrolysis gas chromatography (PGC). The influence of temperature rise time, pyrolysis temperature and pyrolysis time on the yield of volatile organic pyrolysis products was studied. The use of short pyrolysis time (8 msec) and a high pyrolysis end temperature (1300 degrees C) was found to provide a high yield. In consecutive analyses of the test organism, under the pyrolysis conditions indicated, the standard deviation of the total yield of volatile organic products was +/- 7%. The pyrolysis technique described suggests that few secondary reactions of the pyrolysis fragments occur.

摘要

采用热解气相色谱法（PGC）对脆弱拟杆菌进行分析。研究了升温时间、热解温度和热解时间对挥发性有机热解产物产率的影响。结果发现，使用较短的热解时间（8毫秒）和较高的热解终温（1300摄氏度）可获得高产率。在指定的热解条件下对受试生物进行连续分析时，挥发性有机产物总产率的标准偏差为±7%。所描述的热解技术表明热解碎片的二次反应很少发生。
